Mechanical Stirrer

ESCO Airstream vertical laminar Flow Clean Benches LVG offer proven protection for your samples and processes where operator protection is not required. Vertical laminar flow offers certain tangible advantages over horizontal flow clean benches (which may be conventional in some parts of the world), such as lower energy consumption (40% of conventional systems) levels through the use of exclusive motorized impeller technology and less airflow turbulence (especially when large objects are used in the work zone). In fact, the negative pressure filter mounting system employed on these models is widely recognized to be superior to that of conventional horizontal flow clean benches.

ISO Class 3 air cleanliness within work zone as per ISO 14644.1 (Equivalent to Class 10 as per US Federal Standard 209E, 10 times “cleaner” than the usual Class 100 classification on clean benches offered by the competition).
High-quality polyester pre-filter and main ULPA filter with a typical efficiency of 99.9997% at MPPS and 99.9998% at both 0.3 and 0.12 microns provide the best product protection in the world; typical main ULPA filter lifespan is more than 3 years depending on the usage of the clean bench.
Mini-pleat separator-less ULPA filter technology reduces energy consumption and delivers increased laminar airflow uniformity for better product and cross contamination protection.
Integral filter metal guard on both sides prevents accidental damage to ULPA filter; seamless filter gasket is permanently melded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included.

The high-performance compound microscope for every laboratory with fixed, pre-centred Koehler illumination.

The KERN OBF and OBL models are excellent, stable laboratory microscopes for all common routine applications
Through the simple Köhler lighting, the adjustable field diaphragm and a pre-centred and height-adjustable Abbe condenser with adjustable aperture diaphragm, these microscopes produce superb images in both the light and dark field
As standard, these microscopes, depending on the model, are fitted with wide-field eyepieces, achromatic, planachromatic or infinitely corrected E-Plan lenses
These binocular microscopes are fitted with a dioptre compensation
A trinocular head is available as an option, so that you can connect a camera
A revolving unit for up to 4 lenses and a large specimen stage are included with delivery as standard
The following optional accessory items are available: Various eyepieces, lenses, a complete polarisation kit, a phase-contrast unit as well as complete HBO and LED fluorescence kits etc.
The light is provided by a 20 Watt halogen lighting unit or by a 3 Watt LED version as an alternative
A central feature of this adaptable, robust microscope range is the stable mechanism which can be adjusted precisely
